WATER-DISGHARGE VALVE.

Application filed January 19,1923.

This invention relates to discharge valves and more particularly to discharge valves adapted for use in connection with irrigation ditches, reservoirs, or flumes, and an object. of the invention is to provide a discharge valve of extremely simple construction and which may be readily opened or closed and whi'ch may be automatically controlled by variation of the head of water in a reservoir, flume, or ditch.

Other objects and advantages will be made manifest in the following specification of an embodiment of the invention illustrated in the accompanying drawings, wherein- Figure 1 is a vertical section of a portion of the outlet wall of a reservoir in which the improved valve is mounted.

Fig. 2 is a horizontal section through the center of the outlet and shows the valve in plan.

F 3.3 Stilt.

Fig. -t is a vertical section showing the valve as combined with a hydraulically operated controlling mechanism.

Fig. is an outside or front elevation of the valve apparatus.

The valve is shown as arranged in combination with a wall lV which may represent a portion of a reservoir, tiume or ditch, having a discharge outlet 0 which preferably is of cylindrical form, and in the outer end of the outlet is arranged a valve seat consisting of a. section of a spherical shell 2. This shell is provided with a front flange 3 and with webs 4 which may be embedded in the wall Vt. The valve seat 2 is further provided with a plurality of substantially radial guide ribs 5 having inner parallel edges 6 to receive and guidably support a valve head to be described hereinafter.

Secured on the face flange 3 of the valve seat is a yoke-shaped frame 7 having a central hub 8 and being fastened as by bolts or other means 9 to the front flange of the valve seat. Slidably guided in the central hub 8 of the frame is a valve stem 10 on the inner end of which is secured a valve preferably hollow, consisting of central section 12 with a transversely curved exterior peripheral face and having an inwardly extending conical nose 13 and a rearwardly ex temling conical hub 14 secured to the inner end of the stem 10.

Pivotally connected as at 15 to the outer is an inside face view of the valve Serial No. 613,644.

end of the stem is a lever having a downwardly extending arm 16 which is pivoted at- 18 to a swinging link 19 which is pivoted at 20 on the frame 7. The lever has an upwardly extending arm 17 carrying a nut 21 running on a screw-threaded shank 22, to which is secured a hand wheel 23; the inner end of the shank 22 being turnably mounted in a swinging bearing 24 pivoted on a bracket 25 suitably secured as to the face of the wall W.

In operation of the valve, the hand wheel 23 is rotated, axial movement of the screw shank 22 being prevented, and the nut 21 moves outwardly or inwardly according to the direction of rotation of the hand wheel 23. Assuming an outward movement of the nut 21, this will cause the lever arm 17 to swing outwardly and carry with it the stem 10 and the valve head, the latter moving outwardly toward the coneaved seat 2 which is complementary to the valve.

Preferably, the transverse element of the yoke 7 is of V-shaped cross-section, as indicated in dotted lines in lt ig. 2, so as to divide the stream of water passing through the outlet wall as the valve is open and, therefore, serves to reduce pressure of the water on the lever arms.

During the inward or outward movement of the valve head it is supported on the parallel inner edges of the guide ribs 5 and this prevents undue vibration or oscillation of the valve head and serves to cause a steady accurate movement of the valve inwardly or outwardly. I

As shown in Figs. 4 and 5, the valve may be automatically moved either toward or from its seat, and this may be accomplished by hydrostatic mechanism including a cylinder preferably mounted for oscillation and in which moves a piston 31 connected by a link 32 to the lower end of the arm 17 of the valve operating lever, which in this instance is shown in reversed position. The cylinder 30 is provided at each end with inlet and outlet pipes 83 leading to a fourway valve 34. As shown, the valve is positioned to permit the passage of water from the reservoir through a duct 35, and a pipe 86 attached thereto, and to the valve 84 and from thence into the inner end of the cylinder 80. This results in the outward movement of the piston 31 bringing the valve head to its closed position, as shown.

The automatic closing of the valve is obtained by direct action of a head of water pressure in the reservoir so that as the head of water in the reservoir increases, the valve will be automatically moved to its closed position before the water level reaches the discharge outlet of the valve. Conversely, if it is desired to automatically open the valve it is but necessary to reverse the position of the plug of the four-way valve 34: and this will permit the application of water under pressure to the outer side of the piston 31 and this will be'moved inwardly and the valve opened.

Further embodiments, modifications and variations may be resorted to within the spirit of the invention as here claimed.
